Description
Technical field
The present invention relates to bridge construction field.
Background technology
Large span stayed-cable bridge can be divided into from structural system: tower Liang Dun consolidation system, supporting system (including half floating system),
Floating and tower beam consolidation system.With regard to earthquake, wind and temperature load evaluation of effect: tower Liang Dun consolidates system: rigidity is relatively big, wind resistance
Good, temperature load is big, and antiseismic ability is more weak；Tower beam consolidation system: rigidity is moderate, wind resistance is fair, temperature load is controlled, antidetonation
Ability still has deficiency；Floating and half floating system: rigidity is less, wind resistance is poor, and temperature load is less, and anti-seismic performance is good.
In strong earthquake area, when antidetonation becomes important consideration, the most more employing of large span stayed-cable bridge is floating and half floating system,
Because integral rigidity is more soft, under longitudinal severe earthquake action, girder can produce bigger length travel, this will cause the main bridge of cable-stayed bridge with
Mutually collide between access bridge girder beam-ends, or cause colliding between beam body and abutment, and cause other components such as expansion joint, bearing
Destruction, excessive girder displacement also can produce the biggest tower root moment of flexure and tower top displacement. therefore, float system or half floating body
It is that cable-stayed bridge is commonly installed longitudinal energy-consumption shock-absorption device, to reduce the girder length travel that earthquake produces, the most most common is
Viscous damper, but have that technical sophistication degree is high, reliability is weak, leakage of oil and later maintenance weakness costly.
Summary of the invention
For overcoming above-mentioned defect of the prior art, the present invention proposes techniques below scheme: one is provided with anti-buckling support
Large span stayed-cable bridge anti-seismic structure, it is characterised in that: with bridge floor centrage as symmetrical centre, along girder longitudinally at bottom plane of main girder
And be mounted between bridge tower sill to anti-buckling support.One end of the anti-buckling support of mounted in pairs is connected by connector
In bottom plane of main girder, and the other end is connected to crossbeam end face or side by connector.One end of the anti-buckling support of mounted in pairs
Can be connected with bottom plane of main girder by hinge i, and the other end is connected with crossbeam end face by hinge ii；Anti-buckling of mounted in pairs
One end of support can be connected with bottom plane of main girder by hinge i, and the other end is connected with crossbeam side by hinge ii.With bridge floor center
Line is symmetrical centre, also laterally can be symmetrically installed paired anti-buckling between bottom plane of main girder and bridge tower sill along girder
Support.In this case the one end of the paired anti-buckling support being symmetrically installed is connected to girder end face by connector, and another
End is connected to end face or the side of crossbeam by connector.Hinge can be passed through in the one end of the paired anti-buckling support being symmetrically installed
I is connected with bottom plane of main girder, and the other end is connected with crossbeam end face by hinge ii.The paired anti-buckling support being symmetrically installed
One end can be connected with bottom plane of main girder by hinge i, and the other end is connected with crossbeam side by hinge ii.Above along girder longitudinally
Anti-buckling support is installed can be used in combination with along the girder anti-buckling support of lateral symmetry installation.Anti-buckling support can be with liquid
Antivibrator is used in combination.
It is relatively big that anti-buckling support has initial elasticity rigidity, and the feature that during earthquake, hysteretic energy is strong because of surrender can conduct
Power consumption " electric fuse " uses, and simple structure, the highly reliable and advantage of later stage simple-to-maintain.In regular service conditions
Under, anti-buckling support proper stiffness can make Longspan Bridge close to tower Liang Dun consolidation or supporting system, it is thus achieved that good wind resistance and control
Temperature load processed；Under violent earthquake, anti-buckling support surrenders power consumption, and tower beam is close to floating or half floating duty, fall
Low earthquake load and by hysteretic energy control girder displacement response.Thus overcome simple float system or half floating system
The large span stayed-cable bridge shortcoming that girder length travel is excessive under longitudinal geological process, meets earthquake resistant code requirement.It can be effective
Ground improves vertical, horizontal and the bridge entirety shock resistance of Cable-Stayed Bridge Structure, reaches relatively light in the damage of big earthquake centre, meets emergent operation
The design requirement maybe can repaiied.The present invention can be used for newly-built large span stayed-cable bridge Aseismic Design or existing large span stayed-cable bridge antidetonation adds
Gu, the most also the construction for suspension bridge is offered reference.

Detailed description of the invention
Technical scheme proposes a kind of cable-stayed bridge anti-seismic structure new system containing anti-buckling support, its feature bag
Include: by preventing bending vertical the installation between bridge Xiang Ta, beam of large span stayed-cable bridge (including floating system and the half big class of floating system two)
Bent support, to replace applying more fluid viscous damper, forms a complete longitudinal antidetonation bridge structure new system.Tiltedly
Draw bridge longitudinal direction anti-seismic structure to be equal to traditional cable-stayed bridge system under static load, stress performance close to " tower Liang Dun consolidation " or
" supporting " system, the applicable rigidity of adjustment is to obtain good wind resistance, and controls temperature load.Under severe earthquake action, logical
Cross the surrender of anti-buckling support make Cable-Stayed Bridge Structure earthquake response condition close to " floating system and half floating system ", play anti-
The energy-dissipating and shock-absorbing function of buckling support also can control the earthquake responses such as the displacement of girder.Anti-bending it is provided with between direction across bridge girder, bridge tower
Bent support.Can effectively strengthen cable-stayed bridge Horizontal Seismic ability, it controls main together with standing link stopper, buffer device for collision
The lateral seismic displacement of beam.This new solution can be used for the Aseismic Design of newly-built large span stayed-cable bridge and existing large span is oblique
Draw the seismic hardening of bridge.This anti-buckling support, for improving the anti-seismic performance of cable-stayed bridge vertical, horizontal and entirety, is arranged on vertical
Between bridge, direction across bridge tower, beam, anti-buckling support has the mechanical characteristic of power consumption and not unstability.
It is divided into two types, anti-buckling support to be located at the bottom of girder beam and bridge tower thwart beam top according to the difference supporting arrangement
Face or side, it is common that arrange (with bridge floor center as axis of symmetry) in pairs, be arranged so as to reduce the structure of anti-buckling support own
Making size and prevent eccentric force, stress own is the most reasonable.
Below in conjunction with the accompanying drawings technical scheme is elaborated: main beam structure in the drawings be denoted as 1, crossbeam
Being 2, bridge tower is 3, anti-buckling is supported for 4, and hinge i is 5, and hinge ii is 6.
